TIMER
The G1000 stores an airframe time-in-service timer and displays this time on the MFD EIS
window. To access the timer, press the ENGINE softkey, then press the SYSTEM softkey.
Airframe total time in service is determined by on-ground and off-ground states within the
G1000. When the aircraft is determined to be airborne, the timer starts.
